Good thing all disks these days have data checksums, then!

(50TB+ on ext4 and xfs, and no, no bit rot. Yes, I've checked most of it against separate sha256sum files now and then. As long as you have ECC RAM, disks just magically corrupting your data is largely a myth.)

Less mythic on SSDs than spinning rust, in my experience.

Not particularly frequent either way, but I have absolutely had models of SSDs where it became clear after a few months of use that a significant fraction of them appeared to be corrupting their internal state and serving incorrect data back to the host, leading to errors and panics.

(_usually_ this was accompanied by read or write errors. But _usually_ is notable when you've spent some time trying to figure out if the times it didn't were a different problem or the same problem but silent.)

There was also the notorious case with certain Samsung spinning rust and dropping data in their write cache if you issued SMART requests...
